Also, the awk script used * to convert the assembly output to assym.h is much * smaller and simpler than sys/kern/genassym.sh. * * Both this method and the genassym.cf method have the * disadvantage that they depend on gcc-specific features. * This method depends on the format of assembly output for * data, and the genassym.cf method depends on features of * the gcc asm() statement (inline assembly). */ #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include /* Note: Avoid /usr/include for cross compilation! */ extern void printf __P((char *fmt, ...)); extern void exit __P((int)); #define def(name, value) { name, value } #ifdef __STDC__ #define def1(name) def(#name, name) #else #define def1(name) def("name", name) #endif #define offsetof(type, member) ((size_t)(&((type *)0)->member)) /* * Note: genassym.awk cares about the form of this structure, * as well as the names and placement of the "asdefs" array * and the "nassefs" variable below.
